DANIEL J'. MILLER, OF NEW YORK, N. Y.

CABLE RAILWAY.

$PECIPICATION forming part of Letters Patent No. 332,933, dated December22, 1885.

Application filed July 523, 1884. Renewed July 27, 1885. Serial No.172,846. (No model.)

To all whom it may concern I Be it known that I, DANIEL J. MILLER, acitizen of the United States, residing at New York, in the county andState of New York, have invented certain new and useful Improvements inGable Railways, of which the following is a specification.

My invention is adapted primarily, but not exclusively, for railways inwhich twin cables are employed, said cables being adapted for optionaluse, so that either may be used while theother is under repair, so thatwhen both the cables are in working condition they may be relieved bygripping them alternately with successive cars on the road. Thecarryingpulleys for supporting the cables within the tunnel arepreferably mounted in pairs within a frame attached to the transverseI-beams of the tunnel yoke, the said pulleys having grooves near theiradjacent ends in suitable position to support and guide the cables inthe required position slightly on each side of the center of the tunnel.

In the accompanying drawings, Figure I is an elevation of one of thetunnel-yokes and a pair of the supporting-pulleys, showing theslot-rails and track-rails in transverse section and a grip in end view.Fig. II is a side elevation of the paired carrying-pulleys in positionwithin their frame, showing the mode of connecting the said frame to thetransverse I- beams of the tunnel-yoke. Fig. III is a plan of the partsshown in Fig. II.

The track-rails are shown at 1 resting on castings 2 of the yoke, towhich also the slotrails 3 are firmly secured, and are braced by ties 4,passing at one end through the said slotrails and at the other endthrough the risers of the yoke-castings. The bottom flanges of thetrack-rails l are confined between solid lugs 5 on the yoke-castings andclamp-bolts 6. The paired castings 2 of the tunnel-yoke are connected atbottom by I-beams 7, on

which the paired carrying-pulleys 8 are supported. The said pulleys arecombined, as 5 clearly shown in Figs. II and III, so as to overlap, andare grooved near their adjacent ends to receive and support the pairedcables. Each of the said pulleys is keyed near one end of its shaft 9,said shafts being mounted in bearings in a rectangular frame, 10,notched underneath its ends, so as to rest on the projecting lugsof'knee-irons 11, which are fastened to the I-beams by bolts 12, passingthrough wooden blocks 13, which are interposed between the knee-irons lland I-beams 7, in order to intercept and deaden the noise produced bythe running cables.

Having thus described my invention, the following is what I claim as newtherein and desire to secure by Letters Patent:

1. In a-cable railway, one or more carryingpulleys the shaft or shaftsof which have their bearings in a frame resting on lugs or kneeironsfixed to the transverse I-beams of the tunnel-yoke,substantially asherein shown and described.

2. The combinatiomwith supporting-frames for the rope-carrying pulleys,of lugs or kneeirons bolted to theI-beams and theinterposed blocks ofwood or other comparatively soft material.

3. The combination of the paired carryingrolls mounted in a commonsupporting-frame and grooved near their adjacent ends to receive thecables, substantially as herein shown and explained.

4. A yoke for cable-railway tunnels, constructed with paired castingsconnected at the bottom by transverse I-beams and supporting at top theslot-irons and the track-rails, in combination with tie-rods extendingfrom the respective slot-irons to the risers of the yoke, substantiallyas herein shown and described.
